lThis invention relates to slidable-hinge case- Vment doors and windows -of the generaltype disclosed in my Patent No. 1,973,565, `dated September 11, 1934, 'and-is mainly an improvement on Vthe invention of that application.

The principal y'object here is Vto allow for :re-

. quiredslight variations inzthefclosedfposition of :the sash Vsuch as may betimposed, -*for example, by adding one or more layers of paint on the sash :or windowiirameror Lboth,which would otherwise cause a diierent closing ior alternativelya lack of weather-tightness if the paint layers arelab- :sent or relatively thin.

Rgiis a partial'sectioncorresponding to Fig. z 1 and 'showing a modification.

Y Referring .atfirst toFigs. 1,12fandi3,'which show a wooden 'wvin'dlw although "the :invention would also .apply to those principally of metal construction, IU is a. window frame comprising vertical or side jambs I I, I2, an upper horizontal or head jamb I3 and a lower horizontal jamb or sill member I4. Within and toward the Vrear of the frame, on the four sides thereof, are mounted flange or molding strips I5, to which may be glued felt packing strips I6 to act as a rear stop for the sash and provide a weather-tight joint between it and the frame, although these packing strips are sometimes dispensed with.

I1 is the sash, consisting of the usual frame and a suitable number, such as two, of glass panes I8, said sash being mounted to swing and slide on the window frame. The side toward which the sash swings in its opening movement is considered the front and the opposite side the rear.

The upper and lower jambs are formed with rectangular grooves from end to end thereof, and in each of them is set a channeled metal track I9 of U-section occupying slightly more than one half of the length of the track, and a metal bar aligned with said track and spaced therefrom by a drainage gap and adapted to act at its inner end as a stop for the slidable hinge in the open position of the sash. To the other end of bar 20 is pivoted, by a pin 2|, one end of a guiding link 22 having its other end permanently pivoted at 23 to a metal plate 24 fastened to the horizontal edge of the sash. 'Said link may, as in my afore- 'said application, 'be la spring member slightly bowedftowardthefcorresponding jamb when the "sashis open;y so that its pin 5'2I willbe detachably Sretaine'd ina-'bearing hole in the bar 2t, These V5 guiding vmembers and the sash hinges are of course in `duplicate on the upper and low-er sides vof .the ..sa'sh, exceptfor .the drainage cups which occur at the bottom only. v

In-this embodiment, as infmy aforesaid priorlO application, thelfrontof Athe sash is formedA on its two horizontal edgesvand/its free vertical edge opposite the hinge, and in this case also on vthe edge -adjacent the `vrhinge, -with sealing lips or `flanges overlapping thefront face lof the win-l5 dow frame I0 toform,wlhen the sash is closed-a front weather-seal supplementing'the rear 4seal .formed between the rear'face of the "sash andthe langestrips' I5. Each of the sash plates 24 is pro- Lvi'ded with a verticalhinge-pin 26 occupying 'and 20 .'.mova'ble `onthe guide trackIS and locatedfinthe 'eyeportionlsof albifurcated slidable spring shoe 28`whose two legsengage'fthe vertical-:sides of the -track`I9 lwith a, yielding friction. To permitthe proper seating of Vthe iiange25 at'the hinged .edge 25 yof the sash, the-hinge pin25 is considerably offset zlaterally out-wardzfrom the sash by 'extending' the plate 24 beyond said edge as illustrated, and to accommodate this offset, the corresponding vertical jamb I I of the window frame is formed with a recess or pocket 29 as provided in my aforesaid prior application, into which the extremity of the track I4 is extended and the hinge received in the closed position of the sash.

In accordance with my present invention, the space between the sides of the track I9 is somewhat greater than the width of the eye portion of the spring shoe 28, and this width may be uniform throughout the length of the track, thereby allowing for some lateral movement of the hinge pin 26 within the track in all positions of the sash. That leg 38 of the shoe 28 which contacts with the rear iiange of the track I9 is longer than the other leg 3| which contacts with the front flange of said track, and the contacting end of K the long leg acts as a fulcrum while the short leg acts as a spring tending to force the eye portion 21 of the shoe with its contained hinge pin yieldingly against the rear flange of the track as shown in Fig. 1, thereby providing a tight 'seal between the jamb II and the adjacent sash flange 25 when the sash is closed, notwithstanding the variable thickness of paint layers 32 which may be applied to the sash or Window frame or both. When these paint layers accumulate beyond a certain minimum thickness, the closing movement of the sash will cause the hinge pin to move laterally forward in the track I9 toward the front flange of said track, against the resistance of the spring-shoe leg 3l, as indicated in Fig. 3.

33 is the usual pivoted latch and handle mounted on the rear face of the sash adjacent its free edge and coacting with a suitable keeper or striker plate 34 mounted on the jamb I2 in a gap of the corresponding flange strip I5, and having a cam action on the latch so that the sash may be drawn tightly closed by turning the handle.

Windows equipped with my invention may be shipped unpainted from the factory, with a minimum or zero clearance between the sealing flanges 25 and the jambs when the sash is closed and the shoe eye 2l lying substantially against the rear flange of the track, and under these conditions the sash may also seal tightly at its inner side against the felt strips I 6. When paint is added, its thickness at the meeting faces is accommodated by a forward yielding of the hinge pins 26 in the manner indicated. With paint layers present, the weather seal on the rear side may still be maintained by the resiliency of the felt strips I6, but it is also entirely practicable to rely on the front seal only for weather tightness.

Thus it will be seen that the present invention provides a very simple form of spring hinge permitting a tight weather seal under all conditions, without cramping of the sash and without requiring the use of a separate shoe having a close lateral i'lt in the track.

In Fig. 4 is shown a modification dispensing with the offset hinge and also dispensing with the front weather seal, reliance being had upon a rear seal only for weather tightness. In this case, a hinge track I9 is provided as before, although not extended into a pocket in the jamb I I, together with a spring hinge shoe 28 with long and short legs as before, in the same relation Vto the track and having its eye portion laterally movable therein, but the hinge pin 26 in this case is not oiset from the sash but located closely adjacent to its hinged edge, Within the projected horizontal limits of the sash. It is desirable in this modification to round the rear face of the sash adjacent the inner corner thereof on the hinged edge as indicated at 35, on a cam-like or nonconcentric curve to avoid interference with the corresponding flange-strip I6 as the sash approaches its closed position, but to seal tightly against said strip when fully closed so that the sash may betightly sealed on all four margins of its rear face when it is drawn in at its free edge, the seal being elastically maintained at the hinged edge by the lateral yielding of the pin 26.

The construction may also be modified as shown in Figs. 6 and 7 of my patent heretofore referred to, the improved shoe 28 of the present application taking the place of the shoe of the patent. Various other modifications can be made within the scope of my invention as defined in the claims.

What I claim is:

1. In a window mounting, the combination of a Window frame having a channel guide track, a sash having a hinge pin movable along and also transversely of said track, and a bifurcated spring shoe pivoted to said pin andslidable in the track, said shoe having relatively long and short legs, the latter of which acts as a spring yieldingly opposing the movement of said pin in the direction of opening movement of the sash.

2. A spring shoe for slidable-hinge Windows, said shoe consisting of a bifurcated, single-piece leaf spring having an eye portion for embracing the hinge pin of the sash and a pair of legs extending therefrom, one of which is shorter than the other. Y

3. In a window mounting, the combination of a Window frame having a channel guide track, a swinging sash arranged sothat in closing one edge will swing against the outer face of the frame and overlap it and also having a hinge pin ladjacent said edge and lying in said guide track, a bifurcated spring shoe having an eye portion on the pin of less diameter than the Width of the channel so that the pin and eye have a limited movement transversely of the channel, said spring acting as a shoe slidable in the guide and arranged to yieldingly maintain a sealed relation between the frame and the inner side of the sash at the hinged edge of the latter when the sash is closed.V
